ROCKING-CHAIR.

Application filed April 8, 1925." Serial No. 21,083;

poses. Another object ,of my invention is the provision ofan attachmentfor rocking chairs having a compressible back portion wherein the,movement of the persons body during the :rockingoperation will actuatethe compressibleback portion and this action will be utilized forcompressing air adapted to be usedzinnwarm weatherasa cooling medium. :1l p n.

A further object of my invention is the provision of. a device. setforth above wherein there is included :astorage, chamber. in whichrthecompressed air is. stored v wherein manually operated means isemployedfor utilizing the, air, stored within the 4 chamber as ,a' cooling;medium. r -7.

Referring moreings, itwill-be noted that my improved attachment is preferablyincorporated in that type of rocking chair having ajcompressible backportion, the chair in the present in stance including the usual rockers1,'with the front legs2 and the rear-legs 3, extendparticularly to thedraw- 5 ing upwardly therefrom to supp'ort'the seat 4 and side arms 5.'lher-backisformed of a flexible covering 6 suppo1 -ted uponthe outerends of the coiledsprings 7 and inner ends of which are connected to theback portion 8. From this it will be noted that when the person isrocking in the chair the forward movement of theirocker willghave atendency to cause the backjof the person to'move forwardly allowing thesprings .7 to expand' upon the flexible covering and will com-- pressthe springs 7 uponthe backward hove-I ment, an action which 1s bound totalze'place in rocking chairs having a compressible or flexible back. li 7 In the back portion 8 of the chair atonewayvalve 9 is mounted whichopens into'the chamber 10 between the fiexible meaiissfi and the back ofthe chair "and within this chamber-lsthe transverse partition .11forming the chamber 12 at thetop kind disposed between the chambers 10and 12 within the c .pariia nsl ne aw 'yj e 1e p -i through V mittingthe air to pass into the chamber 12 t, p yentmaeny eekw m vemen Je the ar into the chamberlO, and both valves 9 ;and being springgcontrolled asillusif trated. so; that it will normally retain them n a v et ivp eitiuF e h .e et
